JOINT STRUCTURE FOR PRECAST CONCRETE FLOOR SLAB
PROBLEM TO BE SOLVED: To provide a low-cost joint structure for a precast concrete floor slab, which dispenses with an arrangement place for a cast-in-place concrete construction machine and the like, and which can shorten construction time.SOLUTION: In a joint structure 10, ends 14 of a precast concrete floor slab 12 are joined together. The joint structure comprises: uneven parts 16 which are formed in an uneven shape in a plan view on end surfaces of the ends 14, respectively, and which are fitted to each other via the opposed end surfaces; and PC steel 18 which is arranged in such a manner as to penetrate the fitted uneven parts 16 in a direction along the end surface and which can impart prestress P in the direction along the end surface.SELECTED DRAWING: Figure 1
【課題】場所打ちコンクリートの施工機械などの配置場所が不要で、施工時間を短縮することのできる低コストのプレキャストコンクリート床版の継手構造を提供する。【解決手段】プレキャストコンクリート床版１２の端部１４どうしを継ぎ合わせた継手構造１０であって、各端部１４の端面に平面視で凹凸状にそれぞれ形成され、相対する端面で互いに嵌合している凹凸部１６と、嵌合している凹凸部１６を端面に沿う方向に貫通する態様で配置され、端面に沿う方向のプレストレスＰを付与可能なＰＣ鋼材１８とを備えるようにする。【選択図】図１
